Verdict

The call

The clearest difference is rating: Epson iProjection at 4.3 against ViewSonic Projector's 2.7. Epson iProjection also leads on ratings volume (3.4K vs 12). ViewSonic Projector's advantage is review sentiment (50% vs 20%) and iOS requirement (12.0 vs 15.0). On price, update cadence, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Epson iProjection holds the better App Store score, 4.3 against 2.7. That said, the two scores are not equally well evidenced: Epson iProjection has 3.4K ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 20% of Epson iProjection's written reviews are positive against 50% of ViewSonic Projector's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Epson iProjection ships an update every 6 months, ViewSonic Projector every 3 months. The most recent releases landed on October 13, 2026 and September 29, 2026 respectively.
